Question regarding rims for the M03. How is everybody's experience with the rims from Cross and/or 3 Racing? I see that they are priced per 8 pcs at a price similar to other manufacturers rims for 4 pcs, or even 2 pcs in some cases. Is this a "you get what you pay for" thing? I'm looking to run my M03 on a carpet track and figure on doing a little experimentation with tires so saving a little on rims until I get that "magic" set-up down is a nice thing.
